IMPROVEMENT IN PICKET-POINTERS.

To all whom it may concern:

Be it known that I, JOHN W. MINOR, of Middleborough, in the county ofPlymouth and State of Massachusetts, have invented a new and ImprovedPicket-Pointer; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing forming a part of this specilication, in which-Figure 1 represents a side elevation of my improved picket-pointer. Fig.2 is a transverse section of the same on the line c c, Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to a new machine for pointing pickets and posts,and consists in a general arrangement of parts.

A in the drawing represents a horse or frame, supporting my impro vedpointing apparatus. Its upper beam or piece a constitutes the supportfor the picket B to be pointed. In the lower part of the frame is aslot, b, wherein a box or block, d., is held between two wedges, eandj'. C is a forked lever, straddlin g the beam A, and pivoted, by apin, g, to the block d. Above the beam A the lever carries the knife h,for pointing the picket.

D is an adjustable head-block, against which the end of the picket isplaced. A bolt or pin, 1'., secures the slotted head-block to the upperface of the beam A, but permits longitudinal adjustment of the same.

The picket to be pointed is placed upon the face of the beam A, with itsend against the headblock. The pivot g of the lever C is adjusted higheror lower in accordance with the thickness of the picket, so as to bringthe knife to the requisite height. This adjustment is produced by meansof wedges or keys, c and j', which hold the block at the desired height.The head-block is adjusted toward or away from the lever, according tothe taper to be cut. Then the picket has been properly placed, the leverO is swung on its pivot so as to carry the knife through the end of thepicket against thehead-block. This completes one side of the picket,after which the same is turned and similarly treated until all sideshave been prepared in the desired manner.

Without desiring to claim separately any of the parts composing myimproved machine, what I do esteem as new is- The forked lever C,carrying knife h, verticallyadjustable fulcrum-block d, and theheadblock D secured by screw-bolt c' applied to the supportingbeam A,all constructed, arranged, and operating as shown and described.

JOHN W. MINOR.
